[0049] 1.1 Analysis of Traffic Flow Characteristics of Lane Side Design Form with Transverse Passage

[0050] In the lane side design form with transverse passages, in addition to changing lanes normally, vehicles in the side lanes can also enter the carriageway through the cross passage, which reduces the probability that vehicles in the inner lane cannot enter the carriageway due to congestion in the outer lane, and its traffic conflicts Schematic such as Figure 9 shown.

[0051] Note: m+1, m, m-1 are vehicles running on the carriageway.

[0052] n+4, n-1, and n-3 are vehicles that are parking and dropping off passengers in the outer parking lane.

[0053] n+3, n+1, and n are vehicles that are parking and dropping off passengers in the inner parking lane.

[0054] n+2 means that the vehicle in the inner parking lane is entering the driving lane through the transverse passage.

[0055] n-2 is the inner parking lane vehicle ready to enter the transverse pa...

Abstract

The invention relates to the technical field of road design. For providing a specific method for carrying out guidance on the setting of position and number of a horizontal passageway on a lane side in a major transportation hub, the invention adopts the following technical scheme that: in a method for optimizing the setting position and number of a horizontal passageway on a lane side, the two-dimensional cellular automaton model simulation is taken as a platform, through carrying out analysis on the traffic flow characteristics of a horizontal passageway carrying a lane side design form and carrying out detailed description on the various influences of target functions of stopping models, stopping rules, cells of horizontal passageways and turning paths, a target is subjected to integrated simulation so as to obtain the position and number optimization data of passageway setting. The method disclosed by the invention is mainly applied to road designs.

Description

technical field [0001] The invention belongs to the technical field of road design, and in particular relates to a method for optimizing the position and quantity of transverse passages at the side of a lane. Background technique [0002] In order to meet the growing demand for modern travel, cities have successively built large-scale transportation hubs. As a unique traffic facility in a transportation hub, the research on the related problems of the lane side has been paid more and more attention by scholars at home and abroad. As early as the 1960s, foreign countries began to plan the layout and related research on the laneside facilities of large-scale hub systems. In recent years, with the in-depth study of some microscopic dynamic traffic analysis models based on traffic behavior theory, some urban traffic microscopic simulation systems have been developed. The focus of these studies is mainly on the flow simulation of passengers and luggage in the hub, and there are...
